CR50, CR 65, CR80, CR110, CR140 Installing and connecting the refrigerator

For safety reasons the refrigerator is equipped with an electronic system to

prevent the polarity being reversed. This protects the refrigerator against re-

versed polarity when connecting to a battery and against short circuiting. To

protect the battery, the refrigerator switches off automatically if the voltage is

insufficient (see table below).

Connecting the refrigerator to AC power (accessory)

Note

The CR140 and all US versions are available in DC/AC version

only. Without using a rectifier, these refrigerators can be operated

using a 110-240 V~ current source, in addition to a 12 or 24 Vg

current source.

You can connect the refrigerator to AC power if you use a rectifier

(accessory):

 110 - 240 V: MPS-35

Caution – Danger of electrocution

Never handle plugs and switches with wet hands or if you are

standing on a wet surface.

Warning!

If you are operating your refrigerator on board a boat with a mains

connection of 230-V from the land, you must install a residual cur-

rent circuit breaker between the 230V mains supply and the refrig-

erator.

Seek advice from a trained technician.

Note

Always connect the refrigerator to the rectifier. Otherwise the prior-

ity circuit for the refrigerator will be disabled.

The priority circuit reduces the load on a connected battery by the

rectifier always switching to mains operation if AC power is con-

nected.
